Line Magnetic 219ia vs Mc225

I am currently changing things up my system. I am looking to purchase a tube amp and have narrowed down quite a bit. I am unsure however, whether it would be more wise to go with a SET design or a push-pull design. The two amps in particular that I have in mind are either a Line Magnetic 210ia or 219ia SET 845/300B amplifier, or a vintage mc225 push pull amp with 7591 tubes of course. I waved the idea of a primaluna around but am pretty set on the two amps I’ve mentioned.. More will be familiar with the mc225 than will be with the line magnetic, but they get stupendous reviews and feedback, placing them as some of the best out there, next to shindo etc., in the tube amp world. The 225 obviously has its cult following as well, and is renowned and said by many to be maybe the best Mac amp of all time. (doesn’t matter)... anyway..

I am predominantly a record listener, but also listen to some digital and CD. My source pieces consist of a VPI Classic 2 turntable with a Soundsmith Zephyr 2 cartridge, an OPPO 105, and a Marantz 7701 preamp/ phono stage.

I have sold my previous speakers, and will be picking up a pair of 60’s vertical cornwalls this week. 102db obviously means that i do not have to consider wattage as a factor at all. I listen at low to moderate levels generally. Even 2 watts will have the cornwalls blaring. At this point the consideration is quality of wattage and current. The current will be responsible on the power to drive the 15" bass drivers in the cornwalls way more so than the wattage. The line magnetic SET amps will have no issues driving my speakers as they have large quality made transformers and move tons of current.

Here is the thing. I listen to jazz, classical cello and bass arco works, etc etc. I like soft rock as well. I also listen to very aggressive forms of rock. Hardcore, metal, thrash/speed metal, power violence, sludge, crust punk, etc etc. Those familiar, know what i mean. I am unsure on whether to go with a SET amp or PUSH PULL. Will one suit me better, or does it not necessarily matter, and either should do just fine? I know that the mc225 is known for being tubey, however natural, tight low end etc. The 219ia is known for being extremely transparent, refined, with a bold tight low end, beautiful 300B midrange, etc. Read Steve Huff’s review of this amp if you are unfamiliar. He calls it just about the best amp he has ever heard..... However will it does for the heavier stuff i listen to? This music is listened to on LP form more than less, and is recorded well and many are analog recordings.

Any input by those familiar with these two amps OR with push pull/SET amp comparisons in their own setups, please chime it with advice. I do appreciate it!

You’re welcome, Chris. I would not expect there to be any compatibility issues when using a 6SN7GTB in any 6SN7 application. And it would be very unusual for a 6SN7GTA to not be substitutable for a 6SN7GTB (or one of its modern counterparts which might not have any suffix), although based on the information I see in my Sam’s Tube Substitution Handbook it is conceivable that there could be a few oddball designs in which that might be a problem.

The possibility of an issue would mainly arise, though, if a 6SN7GT (or its VT-231 military equivalent) were substituted for either a GTA or a GTB (or their modern counterparts which might not have any suffix), due to the lower voltage and power ratings of the GT. Especially in a power amp or integrated amp application, where the tube may be driven at higher voltage and power levels than in a preamp or other line-level application.

Also, FYI my GEs are from 1958; I have no knowledge of GEs from other eras.

Enjoy! Best regards,

Watersalas-
Similar situation. I didn't even hear a 219ia until I plugged my own in. I heard the 216 which was loaded with gold lion kt88's through lascalas, and then heard a 518ia through cornwalls.  I decided it would be the 219 or the 508 from there and was pretty sure either would be great and wouldn't really matter, 805's vs 845's both being praised tubes when paired with transformers that drive them properly.  I'd love to hear the 508.

The comments from reviewers and especially owners of the Line Magnetic SET amplifiers is noteworthy.  Consistently there is praise for the very high standard of built quality, fit and finish.  LM is serious about the quality of their output transformers and power supplies.  If country of origin were Japan they'd easily be 3x the cost.  Line Magnetic is unquestionably legitimate High End in design, execution and performance.

Listened to my Original Epic pressing of Pearl Jam’s Vitalogy the other evening. The 219ia smothered any mention of what my previous 500watt SS monoblocks could make of this album. It’s a great album to use as a basis as the songs are dynamic and have a lot of ups and downs in power and presentation.

its funny to see how the discussion of the 'first watt is the most important' is a such a true statement.

I've got a rather simple question. I have been listening to vinyl since getting the 219 but have just been trying some digital through it as of last night with my oppo. My question is, I am running the oppo direct into the 219 and using its pre amp. Prior to the 219 I was running my marantz 7701 with XLR running out of it into my sub. Now that the 7701 is out of the mix, how am I hooking the 219 up to the sub?   I have no idea lol.. someone fill me in here with this simple answer please thank you
